Guessing How Many Missed Callers Would Have Booked: An Honest Estimate

Every tradesperson has felt that sting when the phone shows a missed call from a number they don't know. It's tempting to treat each one as a lost job. It's also wrong. Some were spam, some were suppliers, and some were people who only wanted a price and would never have booked.

If you want a number you can trust, build it from your own records. Here is a cautious way to do it.

Start with the log, not a hunch

Open your phone's call history and look back over a few normal weeks. Skip the odd one with a holiday or a freak cold snap. You want a typical stretch.

Write down every missed incoming call, or screenshot the list. If you also have a landline, a business line or a voicemail inbox, include those. Missed calls that went unrecorded are exactly the ones you'll undercount from memory.

Sort them into piles

Go through the list and put each call in one of these groups:

• Known and not a new job: suppliers, merchants, family, other trades, existing customers chasing something already booked.
• Obvious noise: sales calls, withheld numbers that never came back, wrong numbers, anything you recognise as spam.
• Unknown numbers that could be work: the group that matters.

Only that last pile counts toward lost jobs. Be strict about it. Existing customers are worth a separate note, because they matter, but they are not "new work that walked away".

Check what happened next

For the unknown numbers, look for evidence:

• Did they leave a voicemail? Many people won't, so a lack of voicemail doesn't mean the call wasn't a job.
• Did you ring back, and what came of it?
• Did they text, email or message your business page instead?
• Does the same number appear again later, suggesting they kept trying?

Mark each one as one of these: became a job, talked to me but didn't book, never reached again, or unknown. The first group shows that missed calls can convert. The second shows that plenty of callers are only comparing. The "never reached again" group is where your estimate lives, and it is honestly uncertain.

Apply a deliberately gloomy filter

You can't know what the silent callers wanted, so lean cautious. A few questions help you trim the guess:

• Would this kind of caller normally have turned into paid work for you? Think about the last handful of enquiries you did answer. How many ended in a booking?
• Was the call during hours when you'd have been free to take the job, or in an area you don't cover?
• Is the work you're imagining the kind you actually want, or a small job you'd have declined?

Your own answered-call history is the best guide. If you've turned down or lost a lot of enquiries even when you picked up, the share of missed callers who would have booked should be lower than your optimism suggests.

Then pick a figure you could defend to a sceptical friend, and shade it down a little. It's far better to be surprised by an upside than to build a decision on a number you invented on a bad day.

Be honest about job value

The same caution applies to what a job is worth. Don't use your best-ever invoice. Think about the typical job that comes in by phone, including the small ones, and use something in the middle. If your calls are a mix of quick fixes and larger quotes, write down both and consider using the lower one.

Also remember that value isn't only the first invoice. A good customer may come back, but treat that as a bonus, not part of the base estimate.

Then use a calculator, with your numbers

With your sorted pile, a cautious conversion guess and a modest job value, you have three inputs. At that point a calculator becomes useful rather than flattering. CallCatcher's home page has a calculator for your own missed calls with sliders for missed calls per week, average job value and the share of callers who would have booked. Those are the same three figures you've just worked out, so you can enter them yourself instead of accepting defaults.

Try it twice: once with your cautious figures and once with an even lower conversion guess. If the result still matters to your business in the gloomy case, you have a real problem worth solving. If it only matters in the optimistic case, you've learned something useful too.

Keep the log going

Your estimate gets better with more evidence. For the next few weeks, note down missed calls as they happen and add a line when you find out what became of them. After a month you'll be working from your own habits rather than a guess, and any decision about how to handle calls, whether that's a better voicemail, a quick text reply or something else, will rest on facts you collected yourself.
